AUSTRALIANS have been fascinated by “Big Things” since the 1960s, when statues such as Adelaide’s Big Scotsman and the Big Banana in Coffs Harbour were opened to great fanfare. These supersized structures can be found in other countries, too. The United States is known for its Big Donut, Canada has the world’s largest fiddle, but the attachment to Big Things here has an almost patriotic quality.

Many will recall childhood road trips punctuated by such highlights as a giant Merino sheep or a towering rocking horse, or an assortment of fruits — the Big Avocado, the Big Orange and the Big Mango. When the latter was reported “missing” in 2014, the news made national headlines, only to be later revealed as a publicity stunt.

But in a nation now littered with at least 200 Big Things, there is a sizeable problem. What to do with them as they age and wear out? Many Big Things were built cheaply from concrete and fibreglass — materials that inevitably fade and decay.

Some structures — such as the Big Pineapple, the Big Macadamia Nut, the Big Orange and the Big Prawn — have, in recent times, either fallen into disrepair or struggled to bring in much income.

Then there are others, such as Cairns’s Big Captain Cook, which invite controversy.

The Big Captain Cook stands in a vacant lot on the side of the Cook Highway; its legs show signs of concrete cancer and its paint job is flaky. The hotel that once accompanied Cook is long demolished, and the local community is divided over the appropriate fate of its landmark.

Should he be repainted, or dismantled, or relocated to a place such as James Cook University where, in 2006, students petitioned for his adoption? (Since the university is named after Cook, they thought it would be a good match.) Earlier this year, he was draped with a large Sorry sign to coincide with Australia Day. Indigenous artist Munganbana Norman Miller has proposed the Cook statue be given a Big Boomerang to hold.

Then there is South Australia’s “Larry” the Lobster. Created in 1979, the 17-metre fibreglass crustacean has been on the market intermittently since the late 1980s and reportedly needed repairs. The state government offered $10,000 to help in late 2015.

The Lobster was recently the subject of a nationwide fundraising campaign #PinchAMate led by radio hosts Hamish and Andy. Earlier this month, Larry, who comes with a restaurant attached, failed to draw a bid at auction. But its owners said they were still hopeful of selling Larry, which recently had a $50,000-plus makeover.

Yet while some Big Things, such as the Big Orange (Berri, South Australia) and the Big Macadamia Nut (Nambour, Queensland), sit abandoned, communities continue to build new monuments to attract tourists to remote corners of Australia. The Big Golden Gumboot in Tully, the Big Bogan in Nyngan and the Big Meat Ant in Augathella are examples of the new generation of local symbols.

On the one hand, we can hardly begrudge a community that wishes to unite around a wonderfully kitschy piece of public art. On the other, we have to question why local authorities allow new structures to go ahead when these same local authorities may be asked to take on their upkeep in 30 years’ time.

One of Australia’s most beloved Big Things, the Big Pineapple in Nambour, was built in 1971. It was once a necessary pit-stop on the Queensland coastal tourist trail. In 1983, even Prince Charles and Princess Diana visited it. But in recent years the number of visitors to the Big Pineapple has fallen dramatically. It has been for sale several times since 1996, and even closed for a period during 2010-2011.

In 2009, the Big Pineapple was added to the Queensland State Heritage Register, giving it some legal protection. This move also imposed an expectation that the owners would maintain the structure for future generations. Some saw this as a victory, but for others — including the owners at the time — the listing was a burden that limited opportunities for commercial success.

The sheer volume of Australia’s Big Things makes it impossible to guarantee that all will survive. More local authorities will inevitably face emotive public debates, akin to the furore over the Ballina council’s threatened demolition of the Big Prawn in 2009. (In that instance, the crustacean was bought by Bunnings, which kept it as part of a redevelopment of the property it was attached to.)

One man’s trash is another man’s Big Pineapple. These are undeniably public landmarks of sociocultural significance, and some — like the Pineapple — warrant preservation.

Still, heritage bodies and governments will need to make difficult, and probably unpopular, decisions that may likely send some of our Big Things to the scrap heap.

At the time they were built, it was already clear that Big Things typically have an expiration date.
